plural of partial differential equation

plural of ordinary differential equation

a thermal analysis technique in which a tiny sample pan is heated together with an empty reference pan and the difference in heat flow between the two measured as a function of temperature.

(calculus) An equation involving the derivatives of a function of only one independent variable.

(calculus) A differential equation that involves the partial derivatives of a function of several variables.

(physics, chemistry) The branch of materials science that studies the temperature dependant properties of materials compared with some reference material.

(physics, chemistry) The application of a thermoanalytic technique involving recording any temperature difference between sample and reference materials that are undergoing identical thermal cycles.

plural of differential thermal analysis

(mathematics) The equation that defines the Legendre polynomials: d/dx[(1-x²)d/dxP_n(x)]+n(n+1)P_n(x)=0.

(mechanics) A type of differential that allows its output shafts to rotate at different speeds but can limit the maximum difference in angular velocity between the output shafts, allowing greater torque to be applied to the slower-spinning shaft(s) and generally resulting in better traction than older-design differentials.
